Question

我的Spring Boot应用程序从Oracle数据库中提取了错误的数据，如中所述，它检索了正确数量的行，但内容不正确（数据丢失，[适当地]重复了其他行）。

我是Spring Boot和Oracle数据库的新手。我阅读了很多教程并进行了编码。现在，我尝试创建我的第一个Web服务原型，该原型从Oracle 12c数据库中获取数据并通过HTTP端点对其进行访问。

我使用SQL Developer检查要显示的表的内容，它显示的内容与我的Spring Boot应用程序中的不同。我使用Spring Boot 2.1.4。

我要显示的表包含有关日常运行cronjobs的信息。

这是控制器

import de.dat.verguetung.entity.DailyJobsEntity;
import de.dat.verguetung.service.DailyJobsService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import java.util.List;

@CrossOrigin(origins = "http://localhost:4200")
@RestController
@RequestMapping("/dailyjobs")
public class DailyJobsController {
    @Autowired
    DailyJobsService dailyJobsService;

    @CrossOrigin(origins = "*")
    @RequestMapping(value = "/all", method = RequestMethod.GET)
    public List<DailyJobsEntity> getAllDailyJobs() {
        return dailyJobsService.getAllDailyJobs();
    }
}

这是我的存储库界面

import de.prototype.entity.DailyJobsEntity;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface DailyJobsRepository extends JpaRepository<DailyJobsEntity, Integer> {
}

这是我的模型

import javax.persistence.*;
import java.util.Date;

@Entity
@Table(name = "LOG_DAILY_JOBS")
public class DailyJobsEntity {

    @Id
    @Column(name = "JOB_TITLE", nullable = false, length = 100)
    private String jobTitle;

    @Column(name = "OK", nullable = false, length = 10)
    private Integer ok;

    @Column(name = "JOB_RESULT", nullable = true, length = 1000)
    private String jobResult;

    @Column(name = "EXECUTION_DATE", nullable = false)
    @Temporal(TemporalType.DATE)
    private Date executionDate;


    protected DailyJobsEntity() {}

    public DailyJobsEntity(String jobTitle, Integer ok, String jobResult, Date executionDate) {
        this.jobTitle = jobTitle;
        this.ok = ok;
        this.jobResult = jobResult;
        this.executionDate = executionDate;
    }

    public Date getExecutionDate() {return executionDate;}

    public void setExecutionDate(Date executionDate) {this.executionDate = executionDate;}

    public String getJobResult() {return jobResult;}

    public void setJobResult(String jobResult) {this.jobResult = jobResult;}

    public Integer getOk() {return ok;}

    public void setOk(Integer ok) {this.ok = ok;}

    public String getJobTitle() {return jobTitle;}

    public void setJobTitle(String jobTitle) {this.jobTitle = jobTitle;}
}

这是我的服务

import de.dat.verguetung.dao.DailyJobsRepository;
import de.dat.verguetung.entity.DailyJobsEntity;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class DailyJobsService {
    @Autowired
    DailyJobsRepository dailyJobsRepository;

    public List<DailyJobsEntity> getAllDailyJobs(){
        return this.dailyJobsRepository.findAll();
    }
}

这是我的主班

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class VerguetungApplication {

    public static void main(String[] args) {
        SpringApplication.run(VerguetungApplication.class, args);
    }
}

该表有156行。该应用程序获取156行。没关系。但是这些行中有95％填充了错误的内容。我有一列名为“ EXECUTION_DATE”。该列的输入范围为2019-04-02至2019-04-16。该应用程序显示执行日期为2019-04-02的每一行。

如果需要，我可以提供有关表内容的更多详细信息。

我希望有人可以帮助我并指出我的错误。在此先感谢：）

编辑2 打印获取的行的代码

@CrossOrigin(origins = "http://localhost:4200")
@RestController
@RequestMapping("/dailyjobs")
public class DailyJobsController {
    @Autowired
    DailyJobsService dailyJobsService;

    @CrossOrigin(origins = "*")
    @RequestMapping(value = "/all", method = RequestMethod.GET)
    public List<DailyJobsEntity> getAllDailyJobs() {
        List<DailyJobsEntity> dJobs = dailyJobsService.getAllDailyJobs();

        dJobs.stream().forEach(job -> {
            System.out.println(job.getJobTitle() + " | " + job.getOk() + " | " + job.getJobResult() + " | " + job.getExecutionDate());
        });
        System.out.println(dJobs.size());
        return dJobs;
    }
}

Answer 1

如果我没记错的话，您的DailyJobsRepository使用ClassTemp2来指示主键ID是DailyJobsRepository extends JpaRepository<DailyJobsEntity, Integer>类型，而您的实体Integer则将ID定义为String类型。：

DailyJobsEntity

jobTitle是实体的主键吗？因为我希望PK的类型为Integer。

为什么JpaRepository.findAll（）方法从Oracle数据库中提取了错误的数据？
